Systematic Investment Plans (SIPs) are promoted as the most disciplined way for ordinary investors to participate in the stock market. The premise is simple: invest small amounts monthly, benefit from rupee cost averaging, and harness compounding.
Campaigns promise that SIPs protect against volatility and help investors “beat inflation and grow wealth.” Yet, despite the hype, a painful reality emerges: SIP investors often underperform the market itself.
While stock indices compound at impressive rates over the long term, SIP investors frequently walk away with lower returns than benchmarks. Some even lose money despite years of disciplined investing. Why does this happen?
This article examines the structural, behavioral, and systemic reasons SIP investors underperform the market, with case studies and global parallels to reveal the uncomfortable truth.
The Market vs the Investor
- Markets Deliver, Investors Don’t: Over 10–15 years, equity markets often deliver annualized returns of 10–12%. Yet, SIP investors’ actual realized returns (XIRR) are frequently far lower.
- Behavior Gap: The difference between fund performance and investor returns is often due to investor behavior, not market failure.
Reasons SIP Investors Underperform
1. Mistimed Entries
- Many investors start SIPs after bull runs, when valuations are high.
- If markets correct soon after, their early contributions see poor returns, discouraging continuity.
2. Premature Exits
- Panic selling during crashes (2008, 2020) leads to redemption at losses.
- Investors rarely stay long enough to see full compounding benefits.
3. Stopping SIPs Midway
- Job loss, financial stress, or disappointment with returns cause investors to stop SIPs prematurely.
- Without long-term discipline, rupee cost averaging never plays out.
4. Chasing Past Performance
- Investors switch SIPs into funds that performed well recently.
- By the time they enter, cycles often reverse, causing underperformance.
5. High Costs and Expense Ratios
- Regular plans pushed by distributors carry higher expense ratios.
- Over decades, even a 1% higher fee compounds into lakhs of lost wealth.
6. Poor Fund Selection
- Many investors are sold thematic or small-cap SIPs unsuited to their risk appetite.
- Such funds swing wildly, amplifying underperformance.
7. Ignoring Tax Impact
- Redemptions within a year trigger short-term capital gains tax at 15%.
- Debt SIPs are now taxed at slab rates, further reducing effective returns.
8. Overcommitment and Liquidity Stress
- Believing SIPs are “safe,” some overcommit beyond their surplus.
- Crashes force them to redeem for emergencies, killing long-term gains.
Case Studies
Case 1: The 2008 Shock
Thousands of investors who started SIPs in 2006–07 abandoned them after the 2008 crash, missing the 2009–2010 recovery. Their realized returns were negative, while the index rebounded strongly.
Case 2: The Mid-Cap Trap (2018–19)
Investors lured into small- and mid-cap SIPs in 2014–2017 saw portfolios fall 30–40% in 2018–19. Many exited at a loss, underperforming even conservative benchmarks.
Case 3: The Pandemic Panic (2020)
During the March 2020 crash, SIP stoppages hit record highs. Investors who redeemed lost 20–30% of their capital, while markets recovered within months.
The Psychology Behind Underperformance
- Loss Aversion
Investors hate losses more than they value equivalent gains. This drives panic exits. - Recency Bias
Investors extrapolate recent trends. They chase funds that just did well or exit when short-term losses loom. - Herd Behavior
News headlines and peer actions amplify panic or euphoria. - Overconfidence
Many believe SIPs guarantee crorepati outcomes, only to be shocked by volatility.
The Industry’s Role
Overpromising Safety
- SIPs are pitched as “safe like FDs but better.”
- This narrative sets false expectations and leads to disillusionment when losses occur.
Cherry-Picked Success Stories
- AMCs highlight SIPs that turned into crores but ignore periods where SIPs lagged or failed.
Distributor Mis-Selling
- Bank RMs push high-commission funds, not the most suitable ones.
Simplistic Calculators
- Online SIP calculators assume fixed 12–15% CAGR, hiding real volatility and tax drag.
The Numbers Behind Underperformance
- A study of Indian SIPs shows average investor XIRR often trails benchmark indices by 2–4%.
- Global studies (DALBAR in the U.S.) reveal retail investors underperform market indices by 4–6% annually due to behavior gaps.
- Over 20 years, this gap compounds into lakhs of lost wealth per investor.
Global Parallels
- U.S. 401(k) Plans: Retail investors withdrew in panic during crashes, missing recoveries and underperforming benchmarks.
- UK Unit Trusts: Aggressive marketing in the 1990s led to underperformance when investors exited early.
- China’s Retail SIPs: Similar mass redemptions during 2015–16 market crashes led to poor realized returns.
Investor underperformance is a global phenomenon, not just Indian.
Warning Signs of Likely Underperformance
- Starting SIPs after overheated rallies.
- Investing in high-risk categories without long horizons.
- Relying only on distributors for fund selection.
- Checking NAVs too frequently.
- Having no emergency fund outside SIPs.
What Regulators Should Do
- Mandate Realistic Projections
Ban SIP calculators that assume fixed double-digit CAGR without scenarios. - Suitability Enforcement
Require RMs to match SIP recommendations to investor risk profiles. - Behavioral Education
AMCs should highlight volatility charts, not just smooth corpus projections. - Transparent Reporting
Show fund performance versus actual investor XIRR in disclosures.
How Investors Can Avoid Underperformance
- Stay the Course
SIPs only work with discipline across full market cycles. - Diversify Across Categories
Don’t put everything into small-caps or thematic funds. - Build Emergency Funds
Keep liquidity outside SIPs to avoid forced redemptions. - Ignore Noise
Don’t react to short-term headlines; focus on long-term goals. - Check Costs
Prefer direct plans with lower expense ratios. - Set Realistic Expectations
Assume 9–11% long-term returns, not guaranteed 15%.
Could Investor Underperformance Hurt SIP Growth?
Yes. If too many investors consistently underperform, SIPs may lose credibility as “the safest way to build wealth.” Disillusioned investors could slow inflows, forcing regulators to clamp down on misleading marketing.
Conclusion
SIPs are excellent tools for disciplined wealth creation — but they don’t guarantee outperformance. In fact, SIP investors often underperform the market due to timing errors, panic selling, mis-selling, high costs, and unrealistic expectations.
The problem is not SIPs themselves, but how they’re marketed and how investors behave. Until discipline is matched with education and realistic planning, the gap between market returns and investor outcomes will persist.
The takeaway is clear: the market rewards patience, but investors punish themselves with behavior.
